Thanks for your reply and sorry for my very stupid error.
I retried with the correct parameters and on both cases (2 gb of ram 
working and 4gb of ram not working) I get only this one more line on 
qemu log:
Start bios (version debian/1.7.3-1-1-ga76c6f1-dirty-20130813_122010-test)

The probable cause is that on xen, seabios doesn't generate some tables 
but it takes the static ones from hvmloader.
